According to multiple websites, in December 2014, Lark captioned the above left image with “Pray for me,” although she has since changed the caption. Her friends responded by letting her know that they would indeed be keeping her in their thoughts.

The former teen star, known to a generation of fans as the adorable, fun-loving character Lisa Turtle, denies anything is wrong, but after a series of bizarre pictures and video, some begin to question if the once child star was sick, suffering from some disease or even if drugs were at play. Voorhies adamantly denied it. Instead, her mother says, she has been diagnosed with bipolar disorder.

Signs and symptoms of bipolar disorder include:

Depressed mood most of the day, nearly every day, such as feeling sad, empty, hopeless or tearful (in children and teens, depressed mood can appear as irritability)

Markedly reduced interest or feeling no pleasure in all — or almost all — activities most of the day, nearly every day

Significant weight loss when not dieting, weight gain, or decrease or increase in appetite nearly every day (in children, failure to gain weight as expected can be a sign of depression)
